SHEARS SHARPENER.

Application filedseptember 9, 1921. Serial No. 499,461.

To all whom it may concern:

Be it known that I, (A TER JoNns, a citizen of the United States, residing at Cleveland, in the county of Cuyahogaand State of Ohio, have invented certain new and useful ln'ipii'ovements'in Shears Sharpeners,

angle, and for otherwise changing the rela-v tion of the elements thereoffor utilizing the entire area of the grinding member so that when one portion of said grinding element becomes worn an unworn portion may be a readily brought into action.

A further object of the invention is to provide a device of this class that is light and non-cumbersome, adapting it to be carried in a pocket of ones wearingapparel.

With these and other apparent objects in view, the invention consists in the construction, combination and arrangement of elements as hereinafter described and pointed out definitely in the claims, reference being had to the accompanying drawings which are made part of the specification, similar characters of reference being employed to designate'corresponding parts.

In the said drawings Fig. 1 is a side elevation of the improved device.

Fig. 2 is a top view.

Figs. 3 and 4: are back and front elevations, respectively. I

Fig. 5 is a back elevation of the supporting bracket detached, and Fig. 6 is a side view of same.

Fig. 7 is a top view of the oscillatable leaf member.

Fig. 8 is a side elevation illustrating a modified form of adjustment.

The embodiment of the invention as shown in Figs. 1 to 7, inclusive, includes a supporting bracket 1 having an upright plain wing 1 and an integral base plain wing 1 a medial loop 1 connecting said wings, with I the angle portion broken out on both sides of said loop forming recesses as shown at 1. A movable plate, or leaf element 2 is provided with loops 2 which are adapted'to fit the recesses 1 and co-a'cting with a pintle 3 ments 1 and 2. A screw 3 anchors the pintle 3 in the loop 1... An arcuate screw .41 having the pintle 3 as its radius center, isiattached to the base element 1 This screw passes through an aperture '2", Fig. 7 and has a knurled adjustment member 5 threaded thereon below the member 2, said member 5 bearing on the underside of the member 2 which passes through said loops 2* and loop '1", forms a hinge connection between the eleand operative between, said member 2 and the wing 1 v The movable member 2 carries an abrasive element 6, preferably a flat file, said abrasive element being removably fixed on the upper face of the member 2. Inthe present embodiment the file 6 abuts the loop terminals 2 and is held in fixedcondition by the pivoted finger 7 being operated on by a cam element 8. It will be understood, however, that the abrasive element 6 may be anchored to the member 2 by other adjustable means without departure from the broad principles 1 of the invention.

A guidemember 9 is attached to the upright bracket element 1 said guide being vertically adjustable through the medium of set screws 10 operating in slots 1 and having a forward, and back adjustment by means of shims 11 which are adapted to be inserted between the member 9 and element 1, the screws 10 passing through apertures provided in said'shims. In service the shear blade, which is indicated by broken lines in Fig. 1, is given a reciproc'ating movement with the cutting edge bearing on the abrasive element 6 and guided by the element 9' thereby grinding the edge of the blade on an angle corresponding to the angular adjustment of the member 2. The fore and aft adjustment of the guide element 9 shifts the shear blade relatively to the grinding element, and this together with the possibility ofremoving and replacing the member 6 in a reverse position, either end for end, or laterally, provides economy,by the utilization of the entire abrasive area of saidmember 6.

In the modification illustrated in Fig. 8, the angular adjustment is brought about through the medium of a conical wedge 12 being operated by a screw '13 threaded in a lug 14 which is fixed on the base element 1 'ters Patent is:

sign, andarrangement of arts. being Within the scope ofthe invention asset forth in the appended claims.

What I claim and desire to secure by Let-- Y 1. In a shear sharpening device, thecornbination of a fixed angle bracket; an ad.-

' justable leaf hinged in the angle of said bracket; an abrasive element removably mounted on sald leaf; means for arcuately adjusting the-angular relation of said abraflat plate element and a flat base element, said elements being disposed in angular relation; an oscillatable leaf element hinged in the angle of said bracket; an abrasive element mounted on said leaf; means for adjustably: anchoring said abrasive element; a guide element attached to the upright bracket element; means for vertically adjusting said guide; means for lateral adjust-- ment of said guide; and adjustment means for changing the angular relation of the abrasive element and the guide.-

In testimony whereof I afiix my signa-.

ture.
